Democratic Senator Chris Murphy alleged that he discussed the Trump impeachment with a "handful" of Republican colleagues who, the lawmaker claims, are considering voting to remove Trump from office, MSNBC broke the news on Friday.
Murphy answered affirmatively when asked whether he had spoken with "a single GOP colleague in the Senate who's even considering voting for impeachment".
"It's a small list, on one hand [...] I don't buy this secret ballot thing. If there was a secret ballot, there'd still be only a handful of them that would vote to impeach this guy", Murphy told MSNBC.
In September, House Democrats launched an impeachment inquiry based on a whistleblower complaint alleging that, during a 25 July telephone conversation, Trump asked Zelensky to investigate allegations of the Biden's involvement in the firing of a Ukrainian prosecutor general who had been probing a gas firm in which son Hunter Biden sat on the board.
The White House subsequently declassified what it has claimed to be an unredacted transcript of the July phone conversation. Trump denied any wrongdoing and dubbed the impeachment probe another "witch hunt" against him.
House Dems have followed through on the impeachment inquiry and have conducted dozens of hearings with witnesses testifying under oath.
A two-thirds majority in the Republican-held Senate is required to remove Trump from office, meaning that at least 20 Republican Senators would have to support the move, according to the law.
Trump on Thursday suggested a quick House vote on his impeachment as a means of making way for a Senate trial with a witness list that includes Speaker Pelosi, Congressman Adam Schiff, former Vice President Joe Biden and his son Hunter.
